The AS1337 came in two variants: “A” and “B”. The “A” variant disconnects the battery when in power-down mode (disabled) and “B” keeps battery connected in power down mode.

I ordered plenty of PCBs from PCBWAY. They have excellent quality, good prices and they are reasonably fast. Usually, my customs clearance procedure takes longer than production and shipment.

More details will follow after first tests.
